This makes us more lenient about what we accept for Objective-C
selectors by allowing you to include or not include the trailing colons.
We don't actually need that information, because we have access to the
declaration, so it was only being used for validation, which made the
API harder to use for clients that didn't carefully track zero vs
one-arg selector names.
Also remove the colons from the response, and instead add a bit to say
whether it is a zero-arg or one-arg selector. This makes the response
easier to use for clients that don't care about this information, and
more consistent with the change to the input.

The OncePerASTToken machinery lets us automatically cancel "stale"
requests after a new one comes in. This avoid wasting time processing
requests that have been superceded, which is common for cursor-info, but
sometimes you really want to get results even later, so this commit adds
a way to opt out of the cancellation.
Incidentally, disable cancellation of name translation, which doesn't
really make sense and no one should be relying on that.

We were checking only for the specific loc of the declaration of the
param, but that didn't handle references to a local parameter inside the
body.

If a documentation comment has a - LocalizationKey: field, strip it
out of the documentation body and report it in cursor/doc info with
the key "key.localization_key".

This provides a stream utility for writing to a underlying string buffer multiple string pieces and retrieve them later as StringRef when the underlying buffer is stable.
Extensive cross-language tooling support needs to bridge decl names between two different languages more freely. This SourceKit request is designed to translate Objc names to Swift names and vice versa. Working similarly to cursor-info requisition, the name translation request requires a Swift reference to a Swift/Clang decl, and the preferred name to translate from, and language kind that the given name belongs to. If the translation succeeds, SourceKit service responds with the corresponding name than belongs to the other kind of language.
Newly introduced keys:
“key.namekind": “source.lang.name.kind.objc” | "source.lang.name.kind.swift"
“key.basename”: “name"
“key.argnames”: [“name"]
“key.selectorpieces”: [“name[:]"]
This commit only implements translation from Objc to Swift.
This is necessary when we want to differentiate between type reference
on extension declaration's start, e.g "extension A {}", and other
references of "A". NFC on existing functionality.
The typedef `swift::Module` was a temporary solution that allowed
`swift::Module` to be renamed to `swift::ModuleDecl` without requiring
every single callsite to be modified.
Modify all the callsites, and get rid of the typedef.
Like cursor-info, range info (""source.request.cursorinfo"") answers some
questions clients have for a code snippet under selection, for instance, the type of a selected
expression. This commit implements this new quest kind and provides two
simple information about the selected code: (1) the kind of the
snippet, currently limited to single-statement and expression; and (2)
the type of the selected expression. Gradually, we will enrich the
response to provide more insight into the selected code snippet.
There was a ton of complicated logic here to work around
two problems:
- Same-type constraints were not represented properly in
RequirementReprs, requiring us to store them in strong form
and parse them out when printing type interfaces.
- The TypeBase::getAllGenericArgs() method did not do the
right thing for members of protocols and protocol extensions,
and so instead of simple calls to Type::subst(), we had
an elaborate 'ArchetypeTransformer' abstraction repeated
in two places.
Rewrite this code to use GenericSignatures and
GenericFunctionType instead of old-school GenericParamLists
and PolymorphicFunctionType.
This changes the code completion and AST printer output
slightly. A few of the changes are actually fixes for cases
where the old code didn't handle substitutions properly.
A few others are subjective, for example a generic parameter
list of the form <T : Proto> now prints as <T where T : Proto>.
We can add heuristics to make the output whatever we want
here; the important thing is that now we're using modern
abstractions.
The ArchetypeTransformer isn't actually limited to transforming archetypes
but can transform arbitrary types. Thus, we can rename it to TypeTransformer
